Abstract
Objective To investigate the characteristic changes of serum malondialdehyde (MDA) and supemxide dismutase (SOD) levels in patients who had finger replantation.Methods Blood was drawn from 40 patients at 1,24,48,72 hours and 7,14 days after finger replantation to test the SOD activity and MDA content in the serum.Serum samples were,also collected from 30 healthy adults and analyzed to serve as control.Results Serum SOD activity was significantly reduced,while the serum MDA content increased gradually from 1 hour to 7 days after the operation.There were significant differences when compared to levels in the healthy control (P ＜ 0.05).Serum SOD activity and MDA content basically reached the normal level 14 days later(P ＞ 0.05).Conclusion Detection of serum SOD activity and MDA content after finger replantation can guide medication and prevent probability vascular crisis. Key words: Oxygen radicals; Malondialdehyde; Replant severed fingers; Superoxide dismutase
